Thea for SketchUp provides you with two different ways of controlling Depth of Field (DoF). Sharpness and f-number. In this article we will be looking at both options and also mention the rest of the parameters.
Depth of Field is controlled by the f-number that can be found in Camera Settings. The default value is “Pinhole” and it totally removes the DOF effect from the scene. By selecting any other value, you can control DOF. By default, Camera settings have Auto-Focus enabled and this means that even if you set a custom focus distance, it will be overridden by auto-focus. Unchecking Auto-Focus will make Thea use the focus distance that was set by the user.
